You need AF microadjustment for manual focus too!

False.

When manual focusing the problem is this: you see through the viewfinder at f/4 (or with some bodies at f/5.6) even if you use apperture f/2 or less. The focus shift can cause some misfocusing in that case. But this has nothing to do with AF microadjustment, You cannot correct this phenomenon by any microadjustment.

I am afraid that you did not understand what I was speaking about. I was speaking about theĀ  AF indication while focusing manually. I hope that Canon cameras have active AF system even when focusing manually and tell the photographer when it thinks the picture is in focus. I have never ever used a Canon, so I do not know that.

Not always, unfortunately. The lens (or adapter) must talk to the camera and behave as a normal EF lens. Manual glass with "dumb" mechanical adapter cannot get AF confirmation at all. Better adapters have a small chip that connects with the camera contacts and pretends there is an EF lens mounted (usually 50mm with aperture 2.8 or better).
